Description
Technical Field
The invention relates to the technical field of comprehensive pipe galleries, in particular to a prefabricated assembled comprehensive pipe gallery structure capable of resisting foundation differential settlement and waterproof sealing.
Background
The city underground comprehensive pipe gallery is a structure and an accessory facility which are built in the city underground and used for accommodating two or more types of city engineering pipelines. By integrating various original overground and underground electric power, communication, gas, heat supply, water supply and drainage and other engineering pipelines of a city into a whole and bringing the integrated engineering pipelines into a corridor, the problems of 'aerial spider web' in the city, reduction in road excavation, avoidance of 'road zippers' and the like can be solved. The underground space release system can be managed intensively, the operation cost is reduced, the pipeline safety is guaranteed, and the underground space is released. The cost of repeated repair of the road surface and the maintenance cost of the engineering pipeline are reduced; the integrity of the pavement and the durability of various pipelines are maintained; the contradiction between the pipeline and urban greening is reduced, the urban environment is beautified, and the national infrastructure construction direction of green and sustainable development is met.
The utility tunnel is as a long linear underground space structure, and it can appear longitudinal deformation because of the differential settlement of ground, still will lead to the utility tunnel to appear the crack that runs through the cross section when serious, and this will make utility tunnel's durability and security reduce. In the current joint technology, the problems of non-uniform settlement of the foundation, water resistance, seepage prevention and the like of the comprehensive pipe gallery can not be solved at the same time. Therefore, the prefabricated assembled comprehensive pipe gallery structure which is resistant to uneven foundation settlement and good in waterproof and anti-seepage performance is urgently needed in the field.
Application number CN201710784094.X discloses a prefabricated assembled comprehensive pipe gallery structure for resisting foundation differential settlement, the comprehensive pipe gallery structure comprises at least two pipe joints which are connected by joints with cross sections in a shape of 'hui', the pipe joints and the joints are sealed by water-swelling rubber rings, the pipe gallery joints belong to flexible joints, and damage is easily generated at the joints. The utility tunnel structure has the disadvantage that when the foundation is slightly unevenly settled, the longitudinal stress generated at the joint between the pipe joints easily exceeds the stress limit which can be borne by the water-swelling rubber ring, so that the water-swelling rubber ring fails. The water-swelling rubber circle after inefficacy will not be normal waterproof function of going again, and after water-swelling rubber circle became invalid moreover, because the outside of this piping lane structure does not take waterproof measure, did not lay waterproofing membrane to make the water of piping lane outside infiltrate in the piping lane very easily. Because this piping lane structure has filled water-swelling waterproof powder and self-compaction concrete in the airtight space that water-swelling rubber circle formed at piping lane tube coupling inner wall and water-swelling, in case water-swelling rubber circle became invalid after, there is water infiltration wherein, water-swelling waterproof powder and self-compaction concrete in the airtight space will form a colloid with water mixture and fill airtight space, then this piping lane tube coupling joint between will provide the rigidity through this colloid and fix, the piping lane joint after the rigidity is fixed will no longer can carry out the function of anti ground inhomogeneous settlement.
Although the prior art has utility tunnels that resist differential settlement of the foundation, there are deficiencies because the joints of the existing utility tunnels are partly flexible joints and partly rigid joints. Although the utility tunnel adopting the flexible joint can resist uneven settlement of the foundation, the strength of the flexible joint is weak and the flexible joint is easy to damage. And even can anti subside, but the settlement difference that it resisted is very little, and when great subsidence took place, utility tunnel's joint still can be destroyed, and the destruction condition is serious can not be restoreed even, and the utility tunnel joint after the destruction has water to ooze into in the piping lane easily and causes serious consequence to the piping lane. Therefore, the existing comprehensive pipe gallery foundation differential settlement resisting technology can only be suitable for areas with good geological conditions, hard foundations and natural foundations, and the effect exerted at the soft foundation is extremely small, which is the limitation of the prior art. The utility tunnel adopting the rigid joint ensures the strength of the joint of the pipe gallery, but cannot play a role in resisting uneven settlement of the foundation, so that it is important to develop the utility tunnel which can not only play a role in the natural foundation but also play a role in the soft foundation area and can resist uneven settlement of the foundation.
